IMPROVED LAM P-WlCK REGULATOR.

Specification forming part of Letters Patent No. 56,250, dated July 10, 1866.

To all whom it may concern:

Be it known that we, HERMANN MUND and ERDMANN HOFFMANN, of Chicago, Cook county, State oflllinois, have invented new and Im proved Attachments for Lamps; and we do 5 is a diametrical section through the lamp burner, chimney, and the holder. Fig. 6 is a detached view of the wick-adjuster.

Similar letters of reference indicate corresponding parts in the several figures. 1

The nature of our invention consists in a loose lever for elevating or depressing the wick in the wick-tube, said lever being so applied to the base of the burner that, by a simple vibrating movement of its outer end, the wick can be adjusted and exposed more or less beyond the upper end of its tube, as will be here inafter fully set forth.

To enable others skilled in the artto understand our invention, we will describe its construction and operation.

In the accompanying drawings, A represents a common glass lamp-chimney, and B represents a yoke which nearly encompasses the base of the chimney. This yoke may be constructed of a piece of fiat spring metal by bending the strip of metal, as shown in Fig. 2, and forming two finger-pieces, a a, on its ends. The diameter of the yoke when open should be slightly greater than the diameter of the smallest part of the chimney-base, as

shown in Fig. 4. This yoke is attached to the chimney by springing its ends open sufficiently far to allow the bottom edge of the chimney.

to pass within it. Then upon releasing the ends of this yoke it will contract about the base of the chimney and be permanently attached thereto.

The lamp-burner may be constructed like the common burners for kerosene-lamps, with this exception: The flange or gallery b is bent inward around its upper edge, and a dovetail notch, c, is formed in it, as shown in Fig. 3. This burner is thus adapted for receiving within its contracted gallery I) the circular portion of the yoke B, while the dovetail notch or recess in said gallery receives the outer edges of the projecting handles a a of this yoke.

' As the diameter of the gallery b of the lamptop is somewhat less than thatof the yoke B, it will be necessary to compress the handles a a, and thus contract the yoke sufliciently to admit it within the said gallery and when thus admitted the handles a a are released, so as to allow the yoke to expand and hold itself, together with the chimney, firmly 0n the burner. By again contracting the yoke, as before, it can be detached from the burner and held with the-chimney by means of the handles a a without liability of burning the fingers if the chimney is hot. V 7

Those portions of the yoke at the junction with the two handles are so formed that they spread out beneath the beveled edges of the space 0 when the chimney is applied to the burner, and thus form a firm attachment of' the chimney. One great advantage of our chimney attachment over those hitherto used is that the yoke will hold the chimney centrally upon the burner and prevent any'lateral play or looseness, and when desired to remove the chimney it can be readily done, whether this chimney be hot or cold, by grasping the handles or projections of the yoke.

In Figs. 5 and 6 adevice is represented for ad justing the wick differing from the rotary spurwheels hitherto used. This device consists of a forked lever, g, which has two spurs or forks formed on its inner end and a flat finger-piece formed on its outer end. Itisinserted through a slot through the perforated portion of the burner, so that it can be vibrated up or down, and also moved in a direction with its length. The spurs or forks have vertical slots formed in one side of the wick-tube for their entrance. This wick-adjuster is prevented from being withdrawn from the burner by having its inner portion twisted, so as to be at right angles to that portion which passes through the slot in the burner. By slightly withdrawing the adjuster g and lifting its outer end, then plied to the burner in the nnnner and for the purpose herein set forth.
